Check Digit Verification of cas no
The CAS Registry Mumber 10338-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,3,3 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10338-85:
(7*1)+(6*0)+(5*3)+(4*3)+(3*8)+(2*8)+(1*5)=79
79 % 10 = 9
So 10338-85-9 is a valid CAS Registry Number.

Lewis Acid Catalysis of Ene Addition of Chloral and Bromal to Olefins; Product Studies
Benner, Jill P.,Gill, G. Bryon,Parrott, Stephen J.,Wallace, Brian
, p. 291 - 313 (2007/10/02)
The addition of chloral and bromal to a variety of alkyl-substituted alkenes has been investigated.The effect of the reaction of varying the Lewis acid catalyst and the structure of substrate have been studied.Anhydrous AlCl3 was found to be most effective catalyst, and ene-type adducts were the major products in most cases.Side reactions were observed with the less reactive systems leading, variously, to the formation of trihalogenoketones, hydrohalogenated ene adducts, and cyclic ethers.Conditions for optimising the yield of ene adducts were established in some cases.The trihalogenoketone by-products can be conveniently removed by a Grignard-type reaction.
